Generations

Works together

How the cisco Nexus 3000 Nexus 3548-X connects to servers, storage and the network: 3 ways, with the parts and products on each path.

iSCSI and NVMe/TCP over Ethernet

Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

iSCSI and NVMe/TCP over Ethernet: how it fits together

File storage (NFS and SMB)

Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.

Hyperconverged cluster

Plan at least two 25GbE ports per node to two switches; all-NVMe clusters often move to 100GbE.

FAQ

What is Warp Mode on the Nexus 3548-X?

Warp Mode bypasses standard Layer 2 lookup pipelines to forward packets directly at Layer 2 and Layer 3 with sub-250ns latency.

What is Warp SPAN used for in financial networks?

Warp SPAN mirrors trade market feeds and order traffic with nanosecond-accurate hardware timestamps for compliance and latency auditing.
